MAA Series


Output voltage
MAA1200 power supply units for industrial and special-purpose equipment. Having compact size (250 х 140 х 41 mm) the maximum power output of these units goes up to 1200 W.

They are able to operate under a wide case operating temperature range (-50°C...+85°C). Units have one isolated output channel, remote on/off, and full range of protections (over-current, short-circuit, overheating).

To compensate for voltage drop in conductors of the load there is also a service function of external feedback that allows you to accurately maintain the voltage on the load remote from the converter. The converters of this series employ active alignment of output currents in several units operating in parallel mode for the common load.

Polymer sealing potting ensures reliable protection against external factors and excludes damage to the transformer caused by vibration or contamination by dirt, moisture or salt mist. Enclosure of the units has u-shaped aluminum base.

The PCB of the unit is protected from mechanical and climatic load by a thin-walled steel cover.
